Antimicrobial animal bedding includes a base textile material and a halo active aromatic sulfonamide compound of Formula (I):

##STR00001##

wherein the variables M.sub.2, X, and M are disclosed herein. The resulting animal bedding product maintains antimicrobial properties over extended time periods.

The filter medium is a filter medium which uses a liquid containing oil and water as a separation target, and has a channel for the liquid. The filter medium includes a base constituting the channel, and one or more of nitrogen-containing fluorine compounds which are provided on at least a portion of a surface of the channel. The nitrogen-containing fluorine compound includes an oil-repellency imparting group and any one hydrophilicity imparting group selected from a group consisting of an anion type, a cation type, and an amphoteric type, in a molecule.

A micro-nano structure-based super-hydrophobic fabric and a preparation method therefor are disclosed. A brand-new method of combining carbene polymerization covalent grafting with solid surface self-assembly is used for the first time to prepare a modified fabric having super-hydrophobic and self-cleaning functions, by taking an aliphatic diazo compound and an aromatic diazo compound as monomers for carbene copolymerization to graft a fluorine-containing and phenyl-containing block copolymer having a single-carbon repeating unit onto the surface of a fabric by means of a covalent bond. A carbene polymer is crystallized under the induction of the surface of a fiber to drive self-assembly to construct a hierarchical roughened structure having a micro-nano composite structure on the surface of the fabric, and a secondary structure is a nano-scale mastoid-shaped structure imitating a lotus leaf surface.

Described are polymer particles or polymer fibers covalently bonded to N-chloroamines, N,N-dichloroamines, N-chloro sulfonamides or N,N-dichloro sulfonamides, for removing volatile organic compounds (VOCs) from a space above a wound. The removal of said VOCs is believed to be primarily or predominantly by chemical reaction of the VOCs with the N-chloro or the N,N dichloro group as covalently attached to the polymer. In particular, the functionalized polymer particles or polymer fibers are part of a wound dressing and have the functionality to control, in particular reduce, odor emanating from wounds, without interacting with the wound. The described dressings can be advantageously used, in particular, in the treatment of chronic wounds or infected wounds.
